摘　　要：以糊化木薯淀粉、羧甲基淀粉钠、膨润土、腐植酸钠为原料制备复合黏结剂,以冷压成型工艺制备型煤。测试型煤的跌落强度和干强度,并对型煤的制备工艺条件进行优化,获得综合性能最优的黏结剂配方。The composite binder was prepared by using gelatinized tapioca starch, sodium carboxymethyl starch ,bentonite ,sodium humate as raw materials, and briquette was prepared by cold pressing. The briquette strength and dry strength of the briquette were tested. The preparation conditions of the briquette were optimized, and the optimum binder formulation was obtained.
